Hi, my father is 64 years old. He has been seeing spots in his vision in form of grey circles in the last four days (in his left eye only). He went to his ophthalmologist and he reassured him that the retina is in good shape but he told him that he needs to stop exercising and that he needs to stop holding stuff that weigh too much for a period of one month. He also asked him to visit him immediately if he sees spots during this month. My father plays tennis so does having eye floaters will be an obstacle for him to stop exercising? Thank you.
Yes, floaters can be very distracting. It depends on whether your father sees 1 or so many he can't see well. Here's a description of floaters:
People describe eye floaters as spots, straight and curved lines, strings, or "O" or "C"-shaped blobs. Some people see a single floater while others may think they see hundreds. The lines may be thick or thin, and they sometimes appear to be branched. To most people, they appear grey and darker in color than the background. The density of different eye floaters will vary within an individual eye. Eye floaters may be more noticeable under certain lighting conditions and be more apparent when looking at a bright sky. Floaters are rarely seen in situations with reduced illumination.
Eye floaters are extremely common in adults and are a leading symptom that causes people to see an ophthalmologist. Almost everyone has eye floaters by age 70, although some people are much more aware of them than others. It is unusual for children under 16 years of age to notice eye floaters.
Abnormal eye floaters are associated with the retinopathy of diabetes, retinal tears, retinal detachment, and large degrees of nearsightedness. They occur more commonly in people who have had injury to the eyes, surgery to remove cataracts, or YAG laser surgery after cataract surgery. Tuberculosis, sarcoidosis, syphilis, toxoplasmosis, and acute retinal necrosis of the eye are other inflammatory diseases that are associated with eye floaters. An unusual ocular condition called asteroid hyalosis is also a cause of eye floaters. Primary or secondary tumors in the eye, including lymphoma and leukemia, are associated with eye floaters, but these are extremely rare.
Your father's Dr. is being cautious in case the floaters aren't just from his age, but possibly due to another problem.
